【摘要】 间柱回采过程中，如何确保两侧充填体稳定是一个重要的研究课题。作者对爆破载荷作用下充填体的动应力场、破坏特性、衰减规律进行了一系列试验研究，结果表明布孔参数、起爆顺序、最大一段药量等对充填体稳定均有影响更多还原

【Abstract】 It is an important research program how to ensure the stability of fill mass on both sides during the pillar stooping.A series of tests have been made on dynamic stress field,destructive behavior and attenuation regularity of fill mass in blasting.The test results show that the stability of fill mass is affected by such factors as distribution of blastholes,blasting order and the maximum delay charge,etc.更多还原
